  #Linux NFS service fixed ports and firewall configuration #

1. Install NFS normal service on Linux

2. Modify the / etc / service, add the following (port number must be 1024 or less, and has not been occupied)
    # Local services
    mountd 1011 / tcp # rpc.mountd
    mountd 1011 / udp # rpc.mountd
    rquotad 1012 / tcp # rpc.rquotad
    rquotad 1012 / udp # rpc.rquotad

3. To restart the nfs service
  service nfs restart
    chkconfig nfs on

4. The rpc associated port has been fixed, you can add firewall rules
/ Sbin / iptables -A INPUT -s -p tcp --dport 111 -j ACCEPT
/ Sbin / iptables -A INPUT -s -p udp --dport 111 -j ACCEPT
/ Sbin / iptables -A INPUT -s -p tcp --dport 2049 -j ACCEPT
/ Sbin / iptables -A INPUT -s -p udp --dport 2049 -j ACCEPT
/ Sbin / iptables -A INPUT -s -p tcp --dport 1011 -j ACCEPT
/ Sbin / iptables -A INPUT -s -p udp --dport 1011 -j ACCEPT
/ Sbin / iptables -A INPUT -s -p tcp --dport 1012 -j ACCEPT
/ Sbin / iptables -A INPUT -s -p udp --dport 1012 -j ACCEPT
# Rpc.statd
/ Sbin / iptables -A INPUT -s -p tcp --dport 32768 -j ACCEPT
